CASE STUDY

Disclaimer- We don't have any intentions to challenge anyone's
observations and conclusion. We are too little to do that. So sorry
for the inconvience

Eng. Kishor K. Ade
According to the news papers and critics it is the differential settlement.
But we have observed some other reasons which may have contributed to the
failure.
What could have been the reasons of failure of this
beautiful structure

Eng. Kishor K. Ade
Right part of the
building which is
stable.
But the concrete
quality?

Eng. Kishor K. Ade
Failure of beam
due to poor
quality concrete

Eng. Kishor K. Ade
Failure of beam column joint Failure of column in
between construction lifts

Eng. Kishor K. Ade
Failure of concrete in compression zone Failure of column due to slip
)concrete failure(

Eng. Kishor K. Ade
Smaller size of footings
Change in column size and failure of
column due to crushing of concrete

Eng. Kishor K. Ade
Looking into the situation we have observed some of the reasons
in addition to the differential settlement
1)Poor quality of concrete in compression zones.
2)Smaller size of footings
3)Failure of columns which caused the settlement in stories which created the P-Δ effect.
4)Due to poor quality concrete the section initially designed as under reinforced may have
transformed into over reinforced sections.
All theses reasons may have contributed sudden collapse of building
CONCLUSION
